Gilbert's syndrome (GS) is a syndrome in which the liver of affected individuals processes bilirubin more slowly than the majority, resulting in higher levels in the blood. Many people never have symptoms. Occasionally jaundice (a yellowing of the skin or whites of the eyes) may occur. Gilbert syndrome is due to a genetic variant in the UGT1A1 gene, which results in decreased activity of the bilirubin uridine diphosphate glucuronosyltransferase (UGT1A1) enzyme. It is typically inherited in an autosomal recessive pattern and occasionally in an autosomal dominant pattern depending on the type of variant. Episodes of jaundice may be triggered by stress such as exercise, menstruation, or not eating. Diagnosis is based on elevated levels of unconjugated bilirubin in the blood without signs of liver problems or red blood cell breakdown. Typically, no treatment is needed. Phenobarbital aids in the conjugation of bilirubin and can be prescribed if jaundice becomes significant. Gilbert syndrome...
